Thrush is a health disorder that can occur in various areas of the oral cavity, including the roof of the mouth. Treatment of canker sores on the roof of the mouth is not much different from canker sores that appear in other areas of the oral cavity. You can use topical medications that are widely available in pharmacies or treatment with natural ingredients.

Similar to canker sores in other areas, canker sores on the roof of the mouth can also cause various complaints such as pain, soreness, and difficulty eating. Some types of canker sores can even be very painful and even cause fever and swollen lymph nodes.

Causes of thrush on the roof of the mouth

Canker sores on the roof of the mouth can appear due to a number of things, including stress or injury to the area. This condition may also be triggered and exacerbated by a number of things, such as:

  • Use of nonsteroidal anti-inflammatory drugs.
  • Consumption of acidic fruits and vegetables.
  • Punctured by objects that cause injury such as: sharp tooth surfaces, toothbrushes, braces or other dental equipment that can trigger sores and cause canker sores.
  • Exposure to food allergens, toothpaste or mouthwash.
  • Helicobacter pylori infection which can cause peptic ulcers.

Complex thrush can be experienced by patients with immune system diseases such as inflammatory bowel disease, lupus and AIDS, or in patients with nutritional problems.

How to treat thrush on the roof of the mouth

Canker sores on the roof of the mouth usually heal on their own. However, there are several ways to treat canker sores on the roof of the mouth that you can do to speed healing.

Applying honey on the canker sore area is considered to reduce the pain, size, and redness of the canker sore, as well as help prevent secondary infection. To use it, simply apply honey to the affected area four times a day.

Chamomile tea

Chamomile flowers contain azulene and levomenol compounds which have anti-inflammatory and antiseptic properties. Use a chamomile tea bag to compress the canker sore for a few minutes. You can also use brewed chamomile tea to gargle three to four times a day.

Baking soda solution

Yogurt is believed to be an option for treating canker sores naturally, especially those caused by the H. Pylori bacteria. Because, the lactobacillus in yogurt is considered to help eradicate H. pylori and treat several types of inflammatory bowel disease. To prevent and treat canker sores, you should consume one cup of yogurt every day.

Candy containing zinc

Lozenges containing zinc (zinc) can help boost the body’s immunity to fight the bacteria that cause canker sores. Taking these throat lozenges can also help speed up the healing time of canker sores. To help heal faster, avoid things that can make canker sores worse such as eating acidic foods, brushing your teeth too hard or exposure to allergens.

That’s the cause of thrush on the roof of the mouth and how to treat it. Call your dentist right away if the canker sore is very painful, causes difficulty drinking, is very large, spreads, or lasts more than 3 weeks. Also beware if thrush is accompanied by a high fever.
